Description

  The present invention obtains the optimum soil for greening the rooftop to mitigate the heat island phenomenon, the so-called Kanto Loam red soil from the active field, and what is to be discarded, especially branches and leaves, chicken manure, and building residue The present invention relates to a method for circulating and utilizing a field that restores and activates the field from which red soil has been obtained using, thereby improving the state of use as a field and enabling soil to be obtained again.

Patent document 1 discloses suppressing the heat island phenomenon by cooling the exhaust gas from an air conditioning system using a roof garden. In this reference, it is disclosed that greening is performed by covering the arrangement with a greening member filled with soil for plant growth.

Patent Document 2 discloses an agricultural material and a greening material characterized by adding an agrochemical to a fermentation process or a fermented product of an organic material decomposed by microorganisms.

Patent Document 3 aims at providing soil-related and livestock / vegetable / fruit tree production by microorganisms by using and administering indigenous fermented compost cultured in rice bran for greening, soil improvement and livestock visceral strengthening As an indigenous fungus is collected from rice, rice bran, okara, etc. from topsoil such as mountains, humus and bamboo, and the original fungus is cultivated with rice bran, sawdust, brown sugar, etc. Then, it is disclosed that the rice bran of the same material is mainly cultured and expanded with brown sugar, rice bran, okara, humus, fruit tree scraps, vegetable scraps, etc. to produce indigenous fermentation compost.

  As described above, in order to suppress the heat island phenomenon, it is currently required to green the rooftop of a building. However, hydroponics and cultivation with a greening base material (high-tech soil component) have the disadvantage that it is too costly, and there is also a problem that the roots of the plant cannot be sufficiently produced, so it is also excellent soil It is best to carry in

  Needless to say, the optimum soil is the red soil (Kanto loam layer) of Tabata, where the plants are actually grown.

  In addition, it is also necessary for civil engineering work to effectively treat branches and leaves that are produced as waste after felling trees and garden trees, and chicken manure produced as waste from poultry farmers.

  Therefore, the present invention provides a method for circulating and utilizing a field where the soil used for rooftop greening for the suppression of the heat island phenomenon can be obtained efficiently and without problems, and the red soil, branches and leaves, and chicken manure of the field are effectively used.

  Therefore, the method of circulating utilization of the field according to the present invention is to collect red soil from the field where the crop has been harvested or fallow field, bring it into the rooftop of the building for planting, plant and plant the plant, and red soil is collected. In the paddy field, the branches and leaves and the collected chicken manure are mixed and placed in a predetermined ratio in the red soil of the field, and after aging for a predetermined period, the field is activated to revive the field, and red soil is collected again after the predetermined period has elapsed. It is possible.

  The branches and leaves are preferably cut or crushed into chips. By cutting or pulverizing chips, the volume can be reduced and the mixing state with chicken manure can be improved.

  Furthermore, it is desirable that the predetermined soil is red soil in a field, and it is also desirable that the predetermined soil is residual soil from the building. By using the red soil of the field as it is, the activation of the field is promoted, and by using the residual soil of the building, the effective use of the residual soil of the building becomes possible, and the soil of the insufficient field by collecting the red soil is made possible. It is possible to replenish.

  In addition, the branch leaves and chicken manure are preferably mixed at a ratio of about 30% by weight with respect to the red soil, and the branch leaves are blended at a ratio of 10% by weight to 20% by weight with respect to the red soil, The chicken manure is preferably blended at a ratio of 20% by weight to 10% by weight corresponding to the branches and leaves. At present, this formulation is the most efficient.

  Furthermore, crops may be planted for a predetermined period after the field is revived.

  As described above, according to the circulation utilization method according to the present invention, the field after the red soil is collected is fermented by placing a mixture of branches and leaves discarded in the red soil of the field at a predetermined ratio. Since it becomes a fertilizer, it can revive the fields, improve the soil in the fields, and function sufficiently as a field, and red soil can be collected again after harvesting. The land can be used again and can be recycled. This makes it possible to effectively use discarded branches and leaves, chicken manure, and architectural residual soil, and to collect high-quality red soil.

  This invention collects red soil from a field where crops have been harvested, carries it to the rooftop of a building for the purpose of greening, plants a plant and greens it, and cuts branches and leaves collected in the field where red soil is collected. The chicken manure is mixed and arranged in a predetermined ratio in the red soil of the field, and is aged for a predetermined period to activate the field and restore the field, and red soil can be collected again after a predetermined period. The branches and leaves are cut or crushed into chips. Furthermore, as the predetermined soil, it is possible to use red farmland or remaining construction soil. The branch leaves and chicken manure are mixed at a ratio of about 30% with respect to the red soil. Specifically, the branch leaves are blended at a ratio of 10% to 20% with respect to the red soil, and the chicken manure is mixed with the branch leaves. It is desirable to mix | blend in the ratio of 20%-10% corresponding to. Furthermore, it is possible to plant a crop for a predetermined period after the field is restored.

  In Example 1 of the present invention, 0.1 to 0.2 of chips and leaves and 0.2 to 0.1 of chicken dung were mixed with red soil 1 of the field from which red soil was collected. It is placed evenly on the field, stirred with a cultivator, etc. and allowed to stand for about 2 to 3 months for fermentation. In order to stabilize the soil, it is desirable to cultivate crops in one or two periods.

In Example 2 of the present invention, 0.1 to 0.2 of the leaves and leaves formed in the shape of chips and 0.2 to 0.1 of chicken manure are mixed into the remaining building soil 1 discarded from the construction site. Then, they are placed evenly on the field, stirred with a tiller or the like, and allowed to stand for about 2 to 3 months for fermentation. In order to stabilize the soil, it is desirable to cultivate crops in one or two periods.

  In Example 3 of the present invention, in the field where red soil was collected, the branches and leaves formed in a chip shape were laid so as to be 10% to 20% of the stirring depth with respect to the stirring depth by the cultivator. It is spread over the entire field so as to be 20% to 10% of the stirring depth, stirred with a cultivator, and allowed to stand for 2 to 3 months for fermentation.

  In Example 4 of the present invention, the branches and leaves formed in the form of chips are mixed in a range of 1: 2 to 2: 1, left to stand for about 2 months to 3 months, fermented into compost, Red soil: The field is revived and activated by mixing with the field so that the compost is about 10: 3.

  It can be understood from the following table that the compost and soil in this example are very excellent as soil. Tables 1 and 2 show the results of compost analysis and soil analysis.
